GUN-LOCK.

SPECIIEIGA'.I'.IOJ.\T forming part of Letters Patent No. 440,939, ,dated November 18, 1890.

Application filed November 23, 1889. Serial No. 331,374. (No model.)

-prain the county of Berks, State of Pennsyl- Vania, have invented certain Improvements in Gun-Locks, of which the following is a speci- Lmtication.

This invention relates more especially to double-barreled shot-guns.

The object is to provide such a gun with a simple and eii'ective mechanism which will permit both barrels to be discharged by means of a single trigger arranged to operate upon independent hammers orstrikers. It is applicable both to guns having the usual outside hammers and to the so-called hammerless guns in which the strikers are concealed. Heretofore in such guns a separatetrigger has been provided for each hammer or striker, causing a very objectionable loss of time when it desired to discharge both barrels in succession, and also making the gunner liable t`o press upon the wrongtrigger when only one barrel is ready to be discharged. A

My invention permits both hammers to be operated by rapid successive movements of the same trigger, a shifting-bar being located between the trigger and the hammers, which bar is automatically moved from one hammer to the other. lVhen one hammer only is set, the trigger is ready to operato it.

The invention is fully described hereinafter in connection Vith the accompanying drawings, and specifically pointed out in the i as Figure l is a longitudinal section showing my invention applied to an ordinary gun having exterior hammers. Fig. 2 is a separate view of the shifting-trigger bar. Fig. 3 is a modification, showing my invention applied to a hammerless gun. Fig. 4 is a sectional plan view of the device.

In Fig. 1, A represents the barrels, which are hinged to the breech-frame B; C, the ordinary outside hammers or cocks; D, the stock; E, the trigger-guard, and F the triggerplate.

The scar b of the gun-lock is pivoted to the lock-plate at b', and its nose engages notches d2 in the tumbler d. Only so much of the gun-lock is shown as is necessary to show the application of my invention, the springs and other details being omitted.

Instead of using two triggers, each of which, engages one of the sea-rs b, and thus operates its own hammer, I employ a single trigger a, which is pivoted to the trigger-plate at a2. This trigger is formed with a broad face a at the point which ordinarily comes in contact with the sear, and between said face'and the converging ends of the two sears is interposed an arm c2 of abarc. The latter is pivoted at c to the vertical bolt f, so as to be capable of swinging horizontally. The arm c2 is hinged at c3 to the bar c, so as to have an independent Vertical movement in addition to the horizontal movement of the whole bar. The latteris also provided with a xed arm c4, bent laterally to the right and terminating in an inclined face c5, which is so arranged as to come in contact with the forward edge d of the tumbler d when the latter is moved by pulling back the corresponding hammer C to cock the gun.

The operation is as follows: Both barrels being uncocked,themovable trigger-arm c2 is swung to the left, so as to be interposed between the broad face a of the trigger and the lefthand scar b. by means of asp1inge,which normally presses the fixed arm c4 to the right. New if the lefthand hammer is raised, thus cooking the barrel, the trigger-arm c2 remains in the position described, and a pull 011 the trigger will raise it on its pivotal point cB and with it the lefthand scar b, thus releasing the nose of the latter from the tumbler-notch and causing the discharge of the barrel. If, however, the right-hand hammer is raised, the edge d of the right-hand tumblercomes in contact with the fixed arm c4 of the bar c and pushes it to one side, compressing the spring c and swinging the hinged arm c2 to the right, where it engages the trigger and the rightfhand sear I). As soon as the right-hand barrel is discharged by pulling the trigger, the spring-eis released and automatically returns the aigm c2 to its normal position in engagement with the 1eft-hand scar. It will thus be seen. that when only one barrel is cocked, whetherl right or left, the trigger is ready to operate it. When both are cocked, it first discharges the This is accomplished IOC right barrel and then immediately is made ready for the left. The flat spring H serves to hold the arm c2 always in contact with the trigger.

It is not intended to restrict my invention to the construction above described, as ordinary mechanical skill will readily adapt it to other forms of gun-locks.

In liigjox it is shown applied to a so-called hammerless gun, in which concealed strikers are used, the tumblers G in this case being so formed as to serve also for strikers. Here the pivoted bar'c is swung horizontally by the backward movement of the combined tumbler and striker G, the arm c2 being thus returned to the proper position for discharging the right barrel by the automatic cocking of both, which in this ease is eiected by the raising of the rear ends of the hinged barrels.

Further adaptions and modifications will be readily devised to suit diierent conditions. The form of the shifting-bar and the means of operating it are evidently suseepti` ble of considerable change without departing from the spirit of my invention.

1. In a gun-lock, the combination, with the two hammers or strikers, the sears, and the single trigger, of a horizontally-pivoted bar having its free end intermediate between the trigger and the sears and means, substantially as described, for automatically shifti ng said bar, substantially as set forth.

2. In a do uble-barreled gun having two hammers or strikers and a single trigger, a hori- 3 5 zontally-pivoted bar having a vertically-m0v able arm in engagement with said trigger and one of said hammers and means, substantially as described, for automatically shifting said bar, all arranged and adapted to 4o operate substantially as set forth.

3. In a double-barreled gun having two hammers or strikers and a single trigger, the horizontally-pivoted bar having a vertically-movable arm c2 in engagement with said .trigger 45 and one of said hammers, a fixed arm c4 in engagement with the cooking mechanism, and a spring e, all arranged and adapted to operate substantially as set forth.

4. In a double-barreled gunhavingtwo ham- 5o mers or strikers and asingle trigger, the combination, with the sears b, of the horizontallypivoted bar c, having a vertically-movable arm c2 and a fixed arm c4, springs e and 71.,
